In Queer Street by Fergus Hume

Owain reached his hotel in the early hours of the morning, and finding no one about but the sleepy night-porter, who was just leaving, had no difficulty in getting to his bedroom almost unobserved. Once in that haven he drew a long breath of relief, and wearied by his long tramp, threw himself on his bed without undressing. Notwithstanding his anxiety, which had increased instead of lessening, he speedily fell fast asleep into a heavy dreamless slumber, which resembled lethargy rather than natural repose. It was high noon when he woke, feeling much refreshed and as hungry as the proverbial hunter. Considering the trouble in which he was involved, it was fortunate that travel had steadied his nerves to face the worst, if needs be. The result of his experience of danger led him to prepare for possibilities. He therefore took a cold bath to brace himself, dressed more carefully than usual with great deliberation, and went down to make an excellent breakfast.

As yet the hue and cry was not out against him, so he had ample time to consider his position.
